McCain himself has obviously changed [since the 2000 campaign]; his flipperoos and weaselings on Roe v. Wade, campaign finance, the toxicity of lobbyists, Iraq timetables, etc. are just some of what make him a less interesting, more depressing political figure now -- for me, at least. It's all understandable, of course -- he's the GOP nominee now, not an insurgent maverick. Understandable, but depressing. As part of the essay talks about, there's an enormous difference between running an insurgent Hail-Mary-type longshot campaign and being a viable candidate (it was right around New Hampshire in 2000 that McCain began to change from the former to the latter), and there are some deep, really rather troubling questions about whether serious honor and candor and principle remain possible for someone who wants to really maybe win.
